STARTING DEVICE FOR mrnnuarrcomnusrrou nriemnsf;

Be it known that I, MALcoLM P. Rrn'nri, a citizen of the United States, andfa resi- .dent of Springfield, in the State of.Massa chusetts, have'invented certain new and ful Improvements in Starting Devices fon Internal-Combustion Engines, of wh1ch" the following is a specification.

My invention relates to means for priming the cylinder or cylinders of an internal combustion engine, sofas-to. facilitate starting the engine by cranking, or: obviate crankin entirely by exploding the charge in cylin ers by switching on the spark. j I

The'object of my invention is to provide a simple and reliable means whereby a charge of gasolene,'or similar combustible fluid, may be measured -ofi and then-blown into the cylinder or cylinders of the engine by air under pressure.

A further object is to provide means whereby a separate charge may be measured ofl for each of the cylinders of a multi-cylinder internal combustion engine, and each charge may be delivered to its 'own cylinder by practically one operation.

A further object of myinvent-ion'isto avoid the difiiculties incident to the entrapping of air in the measuring passage or space of the measuring. device which, when retained therein, prevents the, proper meas' uring of thecharge of priming fluid."

A further object of my inventiomis-to' prevent leakage of the measuring dev ce, especially when employed for measurin and delivering'separate charges for the vferent cylinders of a multi-cylinder engine.

To these ends my invention consists in the combinations of apparatus and details of construction hereinafter more p'art1cularly described and then specified in the claims.

In the' following description gasolene is- 'measuring device for supplying in all four cylinders of a multi-cylinder engine.

As will be apparent from the sub-joined description, the measuringdevice, by a simple multiplication of measuring passages, ports and connections, might be used to supspecification e s Patented Feb.17, 1914.. Application filedrebruary 14,1912. s riamaei'asoe;

I 7 4 3 in Fig. 1 indicates the measurin valve pro erly connected by pipe 13' with tl ae tank 2 w ereby the fluid for the measured charges may be supplied through the intake 9,.Figs. 2 and 4:, to the valve for each operation thereof.

1 indicates a tank or cylinder adapted to contaln and store air under pressure and connected by pipe 12 to a suitable inlet or intake 10 for the valve. The tank 1 provides a source of air retained under pressure and ready to blow the char e measured off by the '-valve into the cylin er or cylinders of the engine upon the operation of the valve to measure the charge, and the movement of the latter with its measured charge into po sition where each measuring passage will register with the port or ports supplied from the tank 1.

ing rod 1 to hold the valve'in one or the other of its positions. Preferably said valve A spring as indicated may be employed under the head of the operat- 5 in which it receives the measured charge or charges from the gasolene tank into position for allowing the air from'the storage tank to force the gasolene into the engine cylinder or cylinders and the spring would serve then to return the valve to position for receivingthe measured charge.

- Air under pressure may be provided in the tank 1 by'any means ready for the operation of blowin out the measured charge 5 on movement of the valve to the proper position, but ordinarily, I prefer to employ an air pump indicated at and connected through a check valve with the tank in the manner. shown or' in any other suitable 0 manner.

The measuring device or. valve is prefer ably of the disk type.

6 indicates the disk which worksbetween two finished surfaces in the two parts 7, 7

25 of the casing, said parts being preferably secured together by devices wh1ch 'will hold the disk by spring pressure against said surfaces which latter contain the inlet and outlet ports with which the measuring passages in the disk may be brought into registry in the operations of measuring the fluid and .blowing the same into the connecting ipe or pipes 14 leading to' the engine cylln ers. In the construction shown, the parts 7 and 7 are secured together by bolts 23 having springs 22 applied thereto and pressing against the part7 which thereby acts as a follower plate upon the disk 6 loosely fitted in a recess in the part 7. Through the disks 40 6 are drilled measuring cavities or' passages S, as many in number as the cylinders to be simultaneously supplied, and in each cavity or passage the priming fluid is measured. Four such passages are shown thereby adapting the device to supply four cylinders through the appropriate connecting device 14. On the'inside face of part 7, against which the disk works, are formed ports 9 corresponding in number to passages 8 and communicating with a space or chamber in the case 7 to which the intake 9 is connected. In the part 7 are also provided four outlet ports 11 reaching from .the face against which the disk works to outlets to which the connecting pipes 14 are coupled. The outlet ports 11 correspond in number to the measuring passages 8 and are arranged preferably in alternation with the inlet ports 9 for the gasolene.

.- In the face of the follower plate or portion 7' of the valve casing against which the disk works ports 19 are provided similar to the ports 9 and communicating in the face of said disk with a space opposite the lower end of an enlarged passage 20 extending through the disk and communicating at its upper end with the space into which the gasolene is delivered from the intake 9. A screen may be employed in this passage as indicated to intercept foreign substances in the gasolene. The plate or portion 7 is also provided with air ports or passages 10 extending through the same.

.The measurin assa es 8 with their char es b b b of fluid are adapted to register with the ports 10 when the disk is turned to position in which the said passages register with the outlet ports 11. The ports or passages 10' communicate freely with the "chamber in the head 26 carrying the air intake 10, which head is bolted to the exterior of' the plate 7 and carries, by preference,'a screen 21 for intercepting impurities in the air supply, The spring pressed follower plate presses the disk firmly against the finished surfaces in the casingon which the ports are formed for the ingress and escape of gasolene and this makes a tight joint or fit so that the valve is free from the danger of leakage of gasolene.

By means of the central passage 20 and the ports 19 the measuring passages 01' spaces are placed at both ends in direct connection with the gasolene supply so that any air entrapped in said passages will be readily displaced by the gasolene.

The arrows Fig. 2 show the manner in .which the gasolene flows downward through the screen and passage in'the center. of the valve and upward through the measuring passages 8, displacing air in the latter so that the air may escape throu 1 the gasolene supply into the gasolene tanl x. This is the position of the disk valve while receiving its charge of gasolene. The movement of the disk tobring the passages 8 into regis-v try with the ports 10 and 11, cuts oil' that connection with the gasolene supply in an obvious manner.-

The operation of the apparatus would be as follows assuming that the air tank 1 does not contain air under pressure at the time it is desired to make use of the apparatus for priming the cylinder or cylinders; and that the disk valve normally stands in position to receive gasolenefrom inlet 9 in its measuring passages or spaces 8 which, under this supposition, register normally with the inlet ports 9' at the top of the disk and 19 at the bottom. The air pump will be first operated one or more times as may be required, and the air from the same will pass by-the check valve into the air storage tank. After sufficient pressure is stored in the tank, the operating knob connected to lever 5 may be pressed,

thereby turning the valve and bringing passages 8 with their measured charges of gasolene into registry with the air inlet ports 10 and the mixture exit ports or passages 11. Immediately upon the disk assuming the latter position, the air from the storage tank will blow the charges 1n the passages 8 into the engine cylinders thereby priming the same and each cylinder will receive its appointed or desired amount of priming fluid or mixture. On release of the knob, the valve returns to position for receiving another charge of liquid and, if desired, the operation may be repeated a second time or as many times as found necessary.

It will, of course, be possible in the operation of this device to move the valve with its measuring passages into registry with the air inlet and mixture outlet ports and then operate the pump, but for large engines with a considerable number of cylinders, it is preferable to make use of the tank in which a sufficient supply of air for a large number of cylinders may be stored ready for the priming operation, by operating the hand pump orby other means, it

being impractical to operate by hand or foot a pump large enough to supply at one stroke the necessary amount of air.

Itis found in practice that in charging or priming a number of cylinders at the same time by my apparatus the device operates efficiently, although as in the case, for instance, of a four cylinder engine it might seem that the charge sent into. the two-cylinders, each of which has one valve open, would be wasted. Experience proves, however, that this is not the case, as enough charges stay in these two cylinders to help out the rather weak charge taken from the carbureter during the first cycle.

The dimensions of passage 8 should be such as to hold the mimimum quantity of gasolene required to properly prime the cylinder when same is hot and already contains a mixture that is somewhere near of explosive proportions, the priming then supplying the deficiency of inflammable material. W'hen the 'same apparatus is used to start the engine cold, a greater amount of inflammable material may be supplied by operating the device seve :11 times if necessary.

-Among the advantages of this device are the following. It supplies a definite amount of priming fluid to each cylinder, which amount may be varied by ope 'ating it a number of times as described above. The priming fluid is injected into the cylinder under considerable pressure and under the best conditions for rapidly forming a homogeneous mixture with the contents of the cylinder. It is very simple to operate, and, if used with a suitable priming fluid,-cannot cause conditions that would be likely to injure the engine. valves or other delicate parts that are likely to become clogged or get out. of order. Its

It contains no check construction is such that the valve portion can be easily made tight against leakage and is likely to remain tight in service. When applied to a gasolene engine it may be operated with the same fuel and from the same tank asis used to supply an engine. It'is practically fool proof and needs no care or attention to keep it in working order.

I am aware that it has been before proposed to prime the cylinders of a multicylinder engine from the same priming device,'the latter being organized to measure only one charge which is delivered from the measuring space by airpressure, the mixture being afterward distributed between the various cylinders. In my invention it will be seen, however, that a separate and definite charge is measured off for each cylinder.

What I claim as my invention is:

1. In a priming apparatus for internal combustion engines, the combination of a source of compressed air, a source of priming fluid and a measuring valve having inlet ports connected respectively to the source ofpriming fluid and to the source of air or gas under pressure and outlet ports connected respectively to the cylinders of the engine, and measuring chambers or passages in said valve adapted to connect in one position with the inlet port connected with the priming fluid and in the other position to connect with the source of air and to register respectively with the outlet ports leading to the respective cylinders of the engine.
